• Quick retrieval from earlier learning (Pushes and pulls). Students answer on mini whiteboards.
• Show answers together and note who needs support in the main task.

1. Is this a push or a pull: pulling up your socks? (push / pull) → pullPrompt: Does the thing move away from you or towards you?
2. Which needs a bigger push to start moving? (an empty shopping trolley (cart) / a feather / a full shopping trolley (cart) / a balloon) → a full shopping trolley (cart)Prompt: Which one is heaviest?
3. Pushes and pulls: which statement is true? (A force can make a still object start to move. / A gentle push makes a ball go faster than a hard push. / Opening a drawer is a push. / Things can start moving all by themselves with no force.) → A force can make a still object start to move.Prompt: What can a force do to an object?

• Drop a sheet of paper and a scrunched-up sheet together and ask why one falls faster.
• Share the objective: What did the force do? Start, stop, turn or squash. Read the success criteria together.

• Work through the example out loud, saying why you do each step, not just what you do.
• Example: What does the force do here: a ball bouncing off a wall?
• Step 1: The object kept moving but went a different way.
• Step 2: So the answer is: changes its direction
• Answer: changes its direction
• Pause after each step and ask a student to say what comes next.

• Do these together. Students try each step on whiteboards before you reveal it.
• Use the hints as prompts rather than giving the answer.

1. What does the force do here: a wall stopping a rolling toy? (starts it moving / stops it / changes its direction / changes its shape) → stops itPrompt: Was the object still or moving before the force?
2. In which of these does the force do this: starts it moving? (a wall stopping a rolling toy / hitting a tennis ball back over the net / pushing a toy car off the starting line / putting your foot down to stop a scooter) → pushing a toy car off the starting linePrompt: Picture each action happening.

• Students work on the student sheet. Circulate and check the first two answers of every student early.
• Students who finish: write a question of their own for a partner, with the answer.

The 8 questions are on the student sheet below, with answers in the key.

• Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.

1. What does the force do here: stepping on an empty can for recycling? (starts it moving / stops it / changes its direction / changes its shape) → changes its shapePrompt: Was the object still or moving before the force?
2. In which of these does the force do this: stops it? (a ball bouncing off a wall / stepping on an empty can for recycling / stretching an elastic band / a wall stopping a rolling toy) → a wall stopping a rolling toyPrompt: Picture each action happening.
